Getting ready to order my 24-70 f/2.8 II and want to include a protective filter with my order. I haven't read about any vignetting with this lens using a standard filter but want to make sure I don't need the thin version. Can someone please confirm if a standard filter works without vignetting?

The lens has a fair amount of native vignetting - over 2 stops in the corners. However, filters don't add to that - presumably due to the 82mm filter thread. I tested an XS-Pro mount (3.4mm thick), an F-Pro mount (5mm thick), and the two filters stacked, and didn't see an increase in the optical vignetting in any case.

Here are three shots, one with only B&W xs-pro and one with Heliopan HT slim (no front threads) and onw with the pol stacked on top of the clear filter.

Only Clear

Only pol

Both stacked

Don't forget to scroll sideways or the problem isn't visible

Nothing is done to either image. And that darkening of the outer corners doesn't go away with +100 correction in Lr, and when pushed even more to try and correct it adds a great deal of noise. At this point 24mm becomes useless imo.

Why scroll sideways? I can see the left upper/lower corners without scrolling. If the vignetting is worse in one or two corner(s) than the others, there's likely a slight decentering of an element in the lens.

I had to scroll sideways here at least.

To me it seems quite even when looking at them here, but the very far corners and small area becomes veryvery dark.

I have a standard thickness F-PRO filter with this lens. It is fine. No need for the ultra-slim X-Pro, but it won't hurt either. The "nano" editions are good, as they repel dust a lot more and (presumably) have even less reflection than the MRC ones. I would take the one that is more readily available.

But I'd prefer the "clear" 007 ones over the "UV" 010 ones.

As for polarizers, I recommend standard thickness ones, as they don't vignett either and are much easier to turn than the slim ones.

I use the Heliopan multi coat uv, as on all my lenses, with no problem whatsoever. I like the Heliopan for its brass ring and threads, and well machined so that they do not stick, cross thread, etc. On and off easily without fear of jamming.
